Given the available data suggesting efficacy of bortezomib in combination with doxil in patients with relapsed multiple myeloma (MM), chronic lymphocytic leukemia (CLL), and Non Hodgkin's lymphoma (NHL) as well as the known sensitivity of AML to anthracyclines and in vitro data demonstrating the sensitivity of multiply resistant AML cells to bortezomib, we are proposing the use of this combination in patients with relapsed/refractory AML or elderly patients who are not candidates for standard induction therapy.
